12V 100Ah Deep Cycle Battery, Group Size 31 Battery for RV, Solar, Camping, Cabin, Marine and Off-Grid System, 1150A Max Discharge Current, 3% Self-Discharge Rate

I use these as part of a backup power system for my house. We don't get a lot of power failures here, but we had 3 in a period of a few months a few years ago. I purchased 4 of these to provide backup power in the event of a power failure. These are connected in parallel, and feed a 2,000 watt inverter, giving me about 4.8 kWh of power. I have a power inlet, a shunt, and a 60 Amp breaker, all of which keep this thing offline. I have an interlock on the 60 amp breaker which prevents having that breaker and the mains on at the same time. With this system, I get power on all of the 120v outlets, ceiling fans, bathroom exhaust fans, and the garage door openers during a power failure. We don't get to use the stove, the dryer, or the HVAC during a power failure. We don't get to use the microwave oven, because it's 1800 watts, which puts my DC-side at over 180 amps. I suppose we could use the microwave oven since it never runs for more than about 30 seconds, and never more than about once per day. I have Anderson connectors across the batteries of two vehicles allowing me to quickly connect a second inverter across the car battery to feed energy into the system during the day with the engine running. 4.8 kWh is more than enough to power the house overnight until I can get a car back on the case the next morning. With the cars' alternators, we get about 750 - 1000 W out of the alternators - way plenty to power the house during the day, and top up the batteries. It's no Tesla Power Wall, but it's a LOT better than nothing.

Well built, quality AGM battery holds charge well and performs as well as expected. Beats the hell out of standard lead acid battery for a better relative price. We have a lot of employees who use our equipment and couldn’t be bothered to check fluid level which led us to buy these and I couldn’t be any happier. Seriously, get away from the distilled water fill ups and gain freedom by opting for some of these. You won’t regret it.

I bought two of the 100 amp hour, 12v, agm batteries about 2 years ago for an off grid (boondocked) rv on our property in the mountains and have them connected to two 150 watt solar panels. I have had absolutely NO issues with the batteries and they power everything we need to camp, including providing power to a 700 watt pure sine wave inverter that we use intermittently for our 120v appliances (crock pot, TV...). The battery is heavy, but we do not carry them around so no big deal. I just purchased 2 more for my main rv (full time use), due to price of these I decided not to go lithium just yet. These came charged and showed 12.3v when I connected them up to my system. I have my charger set to: 13.8 (2.3v per cell) for float and 14.4 (2.4v per cell) for cyclic charging. Very happy with the brand and quality!

There are a couple other brands available for more, but this Weize 100Ah battery looks and performs very well. I bought two for emergency backup power to the run the furnace and fridge for a short time in a condo setting where gas generators aren't allowed. I would recommend these over flooded deep cycle as they're cleaner and more durable. Gel batteries won't handle high current and and there's not much information about hybrid gel batteries out there. Those seem like modified AGM batteries, but not sure of the pros/cons for the extra money. To protect my investments, also bought a trickle charger. The LiFePo batteries look superior, but I'm not cycling, and this is just for emergency backup. Just couldn't justify the price. Without the extra BMS circuitry, these AGMs should just "work" when I need them to.

Used it as a replacement house battery for my motor home its been that factory install one

I have two Zohler sump pumps and wanted to use the second pump as backup. The first pump runs 99% of the time because it sits lower. The second is there in case the first one fails. I connected the battery with a 1500 Watts UPS inverter, that I bought from Harbor Freights for $100. The battery is then connected to a battery charger ($20 on amazon)connected to the outlet which keeps the battery fully charged. If power fails the second pump will run straight from the Wayze battery. To test a power outage, I disconnected the first pump from the outlet, then disconnected the battery charger from the outlet. During heavy rain the pump ran from the battery for 10 hrs. Pump was cycling every 30 seconds. I think this is a pretty good battery. Keep in mind this is only to use as secondary system. If you only have one pump then looks for the Ecoflow battery backup which cost around $500 on amazon.

The battery was measured at 13.2 volts on arrival and was packaged very well. So well packed that I saved the packaging for future use. Pictured is the battery attached in parallel with two other Sealed Lead Acid batteries used to store energy on my experimental 12volt solar system. All my batteries are sealed valve regulated lead acid batteries. (You should never use a lithium battery in parallel or series with a lead acid battery because of different charging characteristics. Doing this is likely to cause a fire and ruin the batteries). I also think this battery will work well with the trolling motor on my boat. I am extremely happy with it especially getting a discount on its purchase.

Great price but at a full charge (10amps charging for 10 hours and tested to display fully charged) only runs my 12v (15amp) transfer pump for roughly 15 to minutes. Overly disappointed as my last battery from the local auto parts store ran the same pump for 3 to 4 hours. Item is also not returnable. Do not buy.
